I plan to hit the ATM and don’t convert at the machine. Let your bank convert. And use CC.
years ago in Vancouver and whistler they took US dollars, but they GREATLY APPRECIATED local currently. I used to get my bank to get me $100 before I left, but the exchange rate in doing that is not advantageous, so really it’s just easier to hit a ATM, but when it gives you the two button choice of convert or don’t convert, it’s usually better to hit don’t convert.
